The chemical sand consolidation methods involve pumping of chemical materials, like furan resin and silicate non-polymer materials into unconsolidated sandstone formations, in order to minimize sand production with the fluids produced from the hydrocarbon reservoirs. The injected chemical material, predominantly polymer, bonds sand grains together, lead to higher compressive strength of the rock. Hence, less amounts of sand particles are entrained in the produced fluids. However, the effect of this bonding may impose a negative impact on the formation productivity due to the reduction in rock permeability. Therefore, it is always essential to select a chemical material that can provide the highest possible compressive strength with minimum permeability reduction. This review article discusses the chemical materials used for sand consolidation and presents an in-depth evaluation between these materials to serve as a screening tool that can assist in the selection of chemical sand consolidation material, which in turn, helps optimize the sand control performance. The review paper also highlights the progressive improvement in chemical sand consolidation methods, from using different types of polymers to nanoparticles utilization, as well as track the impact of the improvement in sand consolidation efficiency and production performance. Based on this review, the nanoparticle-related martials are highly recommended to be applied as sand consolidation agents, due to their ability to generate acceptable rock strength with insignificant reduction in rock permeability.
化学固砂方法包括将诸如呋喃树脂和硅酸盐非聚合材料等化学物质泵入未固结的砂岩地层，以尽量减少烃类储层产出流体中的出砂量。注入的化学物质（主要是聚合物）将砂粒粘结在一起，使岩石具有更高的抗压强度。因此，产出流体中夹带的砂粒数量减少。然而，由于岩石渗透率降低，这种粘结作用可能会对地层产能产生负面影响。因此，选择一种能在最小化渗透率降低的情况下提供尽可能高抗压强度的化学物质至关重要。这篇综述文章讨论了用于固砂的化学物质，并对这些物质进行了深入评估，以作为一种筛选工具，协助选择化学固砂材料，进而有助于优化防砂性能。该综述论文还强调了化学固砂方法的逐步改进，从使用不同类型的聚合物到纳米颗粒的应用，以及追踪固砂效率和生产性能提高的影响。基于此综述，强烈推荐将与纳米颗粒相关的材料用作固砂剂，因为它们能够在岩石渗透率降低不显著的情况下产生可接受的岩石强度。
